Why is independent testing of vapor retarders/barriers important?

Independent testing proves by an independent source, which products conform to the testing criteria established by a testing society, usually ASTM International, formerly the American Society for Testing and Materials . Stego Industries believes very strongly in independent testing. Words on a piece of corporate stationary are only as good as the company that backs them.

Stego Industries was the first company in the industry to independently test its polyolefin to all the necessary parameters of ASTM E 1745. At Stego Industries, we are what we say - and we can prove it.
